WOOL CLEANING AND LAPPING MACHINE.'

Specification of Letters latent No 6.051, dated Jamary 23,; y1849.

To all whom t may concern.' A Be it known that I, FRANCIS A."CALVERT, of-Lowell, in the countyiof Middlesexand State of Massachusetts, have invented certain new and useful Improvements in Machinery for Picking, Cleaning, and Forming a Lap of Cotton,-Wool, or other Fibrous Materials, and that the following descriptio-n taken in connection with the accom-` panying drawings, hereinafter referred to,

forms a full and exact specification of the same, wherein I have set forth the nature and principles of my said improvements, byv

which my invention may be distinguished from others of a similar class, together with such parts or combinations as I claim ,and

desire to have l.secured to me by Letters lPatent.

The use and purpose of my improvements, are, to take the cotton or other fibrous material, directly from the willowing.7 machine, (whereit had been only partially cleaned), and, by passing through my apparatus, to pick, open, and move thorin the sequel,) as one element, and in combination therewith, and as a second element, the ordinary lapping machinery, with calender and lapping rolls; and between the burring apparatus and calender rolls, an improved wire cylinderfso'called, havving teeth upon its periphery, which will further pick, and clean, and distribute the cotton more evenlyupon said wire cylinder, prior to its being doffed from the same, and passed through said calender rolls. p

The figures of the accompanying plate of drawings represent my new apparatus.

Figure 1, is an elevation of one side of the machine. Fig. 2, is an elevation of the opposite side. Fig. 3 is a cent-ral longitudinal vertical section. Fig. 4 is a plan, and Figs. 5, 6, 7 8 and 9, are detail views of some of the important cylinders, which will be hereinafter referred to. I

A A A A, in the several figures, represents the frame work of the machine, in vand* upon cylinders and rollers, are arranged. aa, are the feed rol1ers,`wh1ch receive the cotton, &c.,

from an endless, apron inthe ordinary way,

and n delivery it to the pickerl cylinder, b,

which, the bearings or yboxes ofthe several i which is providedwith teeth in the usual way, as rdescribed in my burring machines, patentedin 1841 and v1843.vk From the picker cylinder, o, the cotton, &cl, is picked on, and received by the cylinder, calledthe receiver, and shownin Fig. 3, at 0,' from which receiver, c, it is passed to the cylinder, (l, whichoccupiesthe placey of the fine combcylinder, so called in my burringmachinesgv above referred to, .as patented in 1841 and 1843. Thesefcylinders, c and d, are provided-with teeth, shapedas shown in Fig. 3,

and hooked as in the burring machines, but

Asomewhat differently prepared, the teeth be- A 'ing formed in narrow strips of wire, properly punched outto give the requisite shapey tothe teeth, and wound, and staked in spiral grooves fromleach side of each of said cylinders, c d, to the center thereof; 'the spiralA grooves on said cylinders, c CZ, being shown iii Figs. 6 and 9. But this arrangement or ahy modification thereof, will be shown andV iescribed in another application for a patent for such cylinders, bearing even date.A herewith. The cylinderye, Figs. 3, 4 and 5,

is the saw guard cylinder, as improved and patented by me in 1847 its office being to beat back the dirt, seeds, &c., from the asI cotton on the cylinder, d, to the picker, b,

and from that the said dirt, &c., is dis-l charged in the usual way. The cotton, &c.,

is next doed from the iine-comb-cylinder, d, by the toothed doHer, f, Figs. 3, 4 and 7, and discharged therefrom on to the toothed wire cylinder, g, Fig. 3, above which is a common pressing roller, h, to prevent the` i cotton, &c., from flying off from said cyl-l inder, g.

The portion of the apparatus thus far de-p scribed, should be suitably covered and grated, as is customary with common pickers. This toothed wire cylinder differs from the common wire cylinder, as its name would imply, Vby the addition of teeth, shaped as shown in Fig. 3; said teeth being formed in strips of wire, as hereinbefore suggested, and wound around the longitudi-` nal wires, i z' z' c', 8m., spirally, as shown in Fig. 8, or straight, (as may be. deemed desirable,) in lieu of the wire netting which usually covers said wires, i i z' z', &c., This arrangement of teeth on the cylinder, g, serves, as hereinbefore mentioned, to further clean the cotton or wool, and to distribute the bers of the same more evenly over the said cylinder, preparatory to its passing through the calender rolls, than it would lbe on the wire cylinder in the common picker; because, in the latter it is blown from the f beater to the wire netted cylinder, and the currents of air from one to the other, are liable to, and do cause an uneven lap, and wool cannot be lapped on a wire netted cylinder, but can be, on a toothed cylinder. I shall, therefore, rest one of my principal claims upon a toothed cylinder for forming a lap. Y

From the toothed wire cylinder, g, the

cotton, &c., is doffed, or stripped Vby the` sinallstripping roller, Z, Fig. 3; the cotton, &c., passingover the same and between the several sets of upper and lower'calender rolls, m m n '21 arranged in the ordinary way, as shown in Fig. 3; thence it'V passes over the two adjacent lap rolls, p, and around the upper wooden lap roll, g, about which it is wound, being pressed compactly shaft, r r, in a full sized machine, which v` would be about eight times as large as it is represented in the accompanying drawings,

should make about five hundred revolutions per minute, and the several cylinders and` rollers above referred to, get their proper proportionate motions by the connection of belts, pulleys, spur and lbevel gearing, shown vin thevarious figures; the arrangement for wliichis so palpable from an inspection .of`

the drawings as to require no description.

Having` thus described my improvements; f in machinery, for picking, cleaning, and forming a lapof cotton, &c., I shall state` my claims as follows: i

What I claim as rmy invention, and desire to have secured to me by Letters Patent is- V1. A toothed. cylinder for forming a `lap of cotton, wool or other fibrous material, to

be usedin lieu of the wire netted cylinder as hereinabove set forth.

2. If .alsol claimy the combination of the burring apparatus or an apparatus for open-Y VAing, picking and cleaning cotton and wool;

constructed,l substantially, as` hereinabove described, with the calender and lap rollers the arrangement and combination being as hereinabove set forth, and for the purposes specified. i

In testimony that the foregoing is a true description of my said invention and improvements I have hereto set my signature lthis fourth day of May A. D. 1848.
